The 6.5-300 Weatherby Magnum is a 6.5mm cartridge created by Weatherby in 2016 for the growing 6.5mm long-range rifle market.[2]
Background
As what was then the newest in Weatherby's lineup, this cartridge was designed to directly compete with the 26 Nosler.[3]
Performance
Claimed by Weatherby to be the fastest 6.5mm cartridge available.[4]
Designed in a similar fashion as other Weatherby cartridges, it has a large-for-caliber case capacity, resulting in high velocities. When bullets with high ballistic coefficients are used, trajectories are extremely flat, allowing the projectile to retain a significant amount of energy downrange.[citation needed]
Availability
Weatherby is currently[when?] the only manufacturer of rifles chambered in the 6.5-300 Weatherby Magnum, as well as the only current supplier of ammunition. Brass cases are available from Weatherby and Petersen for handloading.[5][6] Cases can also be formed by necking down .300 Weatherby Magnum brass.[citation needed]
